One of the oddest and most enjoyable things I did in March 2024 was running a POTA rover against the UTC clock while the Sun became angrier and angrier. From difficult contacts and decreasing reports, I had to arrange skeds for the last parks to keep it going.I even tried an activation in the autumn of 2025, with Kp=8. 20 stations in the log, FT8 only.@hamchallenge |
| 2025-05-19 10:42:30 | yo3gnd@mastodon.radio | 31 | Success! | #HC47S Over the air collab games. Add the number from your call to a running total. The last person to post is the person who is hunted, and others have to work him. First come, first serve. If he's unavailable for more than a week, the previous caller returns in the game.Say Fabian starts, DJ5CW. I sked and he sends me the last number (0) plus the one from his call (0+5=5). He posts 5 under the challenge.I now have to sked or be hunted. I'll TX and post (5+3=)8.@hamchallenge |
| 2025-05-19 10:45:30 | yo3gnd@mastodon.radio | 31 | Success! | #HC47S Arrange for a greyline sked. Keep tabs of the signal reports during the whole window of opportunity and see how the signal booms in and fades out. For digimodes, you can either try a keyboard-to-keyboard mode which monitors the sig.al (Olivia, PSK, JS8) or try multiple exchanges on FT8/FT4.From Europe, the greyline lands on different US states at different parts of the year.@hamchallenge |
